HEATING APPARATUS.

SPECIFICATION forming part of Letters li'atent No. 416,614, dated December 3, 1889.

Application filed June 6, 1888. Serial No. 276,203. (No model.)

To all whom it may concern.-

Be it known that I, J oHNJ HOGAN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in HeatingApparatus, of which the following is a specification. These improvements are applicable to that class of radiators in which a series of vertical columns are connected by transverse or lateral connections at the bottom or at both ends; and the object of the invention is partly to facilitate the drainage of the radiator-columns and partly to facilitate the tightening of the connecting-bolt and the setting of. the

radiator-feet.

In the drawings, Figure 1 is an external view of three sections, or so-called loops, shown in side elevation. Fig. 2 is a horizontal section of the same on line 00 at in Fig. 1. Fig. 3 is an end elevation of the parts shown in Fig. 1, and Fig. 4 is a vertical section of the first two loops on line y y in Fig. 3.

a is the cylindrical shell of the column or loop; b, the head at the top of the same, and c the head at the bottom; and d, the feet provided with nozzles d, in which the pipes d are inserted.

The columns are provided'with ribs f and with longitudinal diametrical slots 6, extended between the heads and dividing each column into two semi-cylindrical compart-' ments, which are connected at the top and bottom by the heads I) and a; but the construction of the body of the column forms no part,

of my present invention. Within each head is a transverse passage 1), connecting the two compartments formed within the column by the walls or partitions e, and serving, also, to connect the interior of each column with the adjacent column. The heads I; and c, for the purpose of, joining a series of such sec: tions together, are formed at their opposite ends with circular flanges. 19 provided, re-

spectively, with annular grooves c and annular tongues 0 The groove is preferably made deeper than the tongue, to admit a packing 0 the compression of which by the tongue serves to form an absolutely tight joint. To press the heads of a series of such sections together, certain of such sections,

which would be used at the ends of the radiator, are provided with bridges h, formed across the passages in the heads, and rods 9 are inserted through the transverse passages of all the sections in the, radiator andthrough a hole provided in such bridge, and nuts g are applied to the ends of the rods to draw upon the same and press the sections and their intermediate packings' c tightly to.- I

gether. If the nutwere applied upon the outside of the radiator, it would be difficult to form a steam-joint around the thread, and I therefore seat the nuts inside upon such transverse bridges and gain access thereto by 6 5 I an aperture closed with a plug 2'. I

In Fig. 1 a radiator constructed of three sections is shown, and the two extreme sections would therefore require to be provided with such bridges as are shown in Fig. 4, the plugs i being screwed into the ends of the transverse passages to close the same outside of the nuts g, and thus concealing the nut by a covering which is readily made steamtight, and which may be ornamented in any desired manner. "It has been common heretofore in using such tie-rods to insert the inlet and discharge pipes .in the threaded apertures where the plugs i are shown herein.

In case of leakage between the heads of the 7 several columns, requiring the tightening of the nuts g it would be necessary to disconnect such pipes to expose the tightening-nuts. I have therefore in my construction provided inlet and outlet connections through the bottom of certain of the columns, and substitute the plugs t, which can be removed at any time and the nut tightened without breaking the steam and water connections.

By forming the inlet or outlet through the bottom of the column the drainage from the radiator is made very perfect, and many other advantages are secured. The inlet and out let connections are formed in a casting with the feet intended to support the radiator, and 9 5 to unite such connections with the interior of the radiator the end sections or columns are provided in the bottom with the apertures k, opening downward, to form a connection with the detachable footd. The nozzles d upon 10o the feet are extended laterally and provided with vertical openings Z to connect with the apertures k, as shown in Fig. 4.

The feet are shown secured to the bottoms of the radiator-columns by bolts m, which form a flange-connection for easily attaching or detaching the radiator and the foot. By constructing the pipe-connections in the foot, instead of attaching them directly to the transverse passage 17 in the column, I am enabled to detach the whole or part of the radiator at any time without displacing the steam or water connections of the radiator, which, when carefully fitted andmade watertight, are seriously injured by repeated un screwing. It is obvious that with this construction the feet may be located by measure in a building where the radiators are to be placed, and the supply and Water pipes be connected with such feet before the radiators are applied, thus greatly facilitating the erection of a large system of heating apparatus in caseswhere the radiators are not ready for delivery.

I am aware that it is not new to use a rod having a head and nut applied to bridges within the radiator-section, as in the Patent No. 371,598; but in such construction the nuts can only be reached by first removing the steam pipes. I therefore disclaim the rod and nut, except the connections or heads in which the bridges are located, are provided with removable caps i, as shown in Figs. 3' and 4 of the drawings, to permit the removal of the nut without detaching the steam-connections.

The columns which are provided with the bridges h in my invention are also provided steam-apertures is through their bottoms, by which they are connected with detachable feet having pipe-nozzles in connection with such apertures. The water is thus eifectually drained from the lowest point of the radiator, whilethe capsi afford the means to disconnect any section of the radiator without breaking its connections to the supply and discharge pipes.

Having thus set forth my invention, what I claim is 1. In a radiator, the combination, with a series of columns having transverse connec tions at their lower ends, of the drainingaperture 70, formed through the bottom of a column, and thedetachable foot-piece d, bolted beneath such aperture and provided with the lateral pipe-nozzle d and vertical opening Z, corresponding with the aperture is, as and for the purpose set forth.

2. In a radiator, the combination, with a series of columns having transverse connections at their lower ends, of inlet and outlet apertures is, formed through the bottom of two of said columns, and detachable foot-pieces secured beneath such apertures and provided each with a lateral pipe-nozzle and with a vertical opening corresponding with the aperture in the bottom of the column, substantially as herein set forth.

3. In a radiator, the combination, with a series of columns having transverse connections at their lower ends, of inlet and outlet apertures is, formed through the bottoms of two of said columns, bridges provided within the transverse connections adjacent to the apertures k, a tie-rod and nut applied to the bridges to secure the series of columns together, removable caps applied to the connections at the ends of the tie-rod, and detachable foot-pieces secured beneath such apertures and provided with pipe-nozzles corresponding with such apertures, the whole arranged and operated substantially as set forth.
